    • Using a Phillips #1 screwdriver, remove the eight screws securing the backplate.

    • Don’t try to force screws which won't come out. They are held in place by a stopper on the reverse side. This will not prevent you from removing the backplate.

    Only the bottom left and right screws can be pulled out. Don’t try to force the others.

    • Lift the fan assembly to gain access to the thermal paste. From here, the thermal paste can be wiped away and replaced. Make sure to only apply new thermal paste to the larger die; don't apply any to the smaller one.

    I saw a video on youtube where thermal paste was placed on both the silicon chiplets of the cpu. In this picture; it looks like only the left cpu is getting thermal paste which i believe is an error.

    I had a machine that was thermal throttling / overheating so I added thermal paste to both silicon chiplets.

    Please comment if someone else has any further ideas.

    Also, do not forget to clean off the old paste from the heat pipe/heat sink surface as well.

I replaced the SSD and decided to replace the heat conductive paste too. It was a good move as the paste had completely dried out. The replacement was effortless and the provided instructions were spot on, confirming my assumptions. Lenovo devices are excellent for self-repair.
